Introduction
The QBK series air-operated diaphragm pump is a type of positive displacement pump that operates using compressed air. It uses the movement of diaphragms on both sides to create a pumping action. This pump offers performance comparable to that of GRACO and HUSKEY models, allowing for easy replacement of internal components. The stainless steel construction makes it ideal for use in food-grade applications, especially in the brewing industry, where safety and hygiene are critical. Since it does not require an electrical power source, it is also suitable for environments where electrical hazards may exist.
